Genes affected

ASCC3 (HGNC:18697): (activating signal cointegrator 1 complex subunit 3) This gene encodes a protein that belongs to a family of helicases that are involved in the ATP-dependent unwinding of nucleic acid duplexes. The encoded protein is the largest subunit of the activating signal cointegrator 1 complex that is involved in DNA repair and resistance to alkylation damage. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Sep 2013]

ASCC3 Gene-Disease associations (from GenCC):

• intellectual developmental disorder, autosomal recessive 81

  Inheritance: AR Classification: LIMITED Submitted by: G2P
• intellectual disability

  Inheritance: AR Classification: LIMITED Submitted by: Ambry Genetics

ACMG classification

Our verdict: Likely_benign. The variant received -2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.92).
